RAIL JOINT.

Application filed July 1 7,

This invention relates to rail joints, and the primary object of my invention is to provide rails that may be advantageously used to form atracktor the rolling stock of steam and electric railways, the rails being constructed to provide practically continuous V pounding, jarring and noise incident to rolling stock passing over ordinary rail joints; It is a well known fact that the adjacent ends of rails are very often broken down, cracked or otherwise injured by rolling stock passing over such a joint, and very otten the wheels and other oarts ot' cars are injured because of excessive stresses and strains incident tothe arring and vibration set up by an ordinary rail oint. Tihe design ot' ny rails is siicln that there is an unbroken path for a wheel opposite each joint, and at the joints there is an unbroken support tor the ends of railsso that the rail structure is practically continuous throughout its length and insures satetravel as' tar as the track is concerned. 7 2

Another object oi my invention to pro- .vide a rail structurewherein the web and baseot a rail are made of two inter-locking parts which materially increase the cross sectional area of a. rail web; insure better support for arail head, and afford spaces in the web ot'ithe rail that maybe usedtor other purposes.

A further object oi my invention is to provide a two-part railroad rail wherein the parts-are separated by members which reduce the noise incident to rolling stool; moving on the rail, and these same members may serve as insulators or means of bonding 1'ails,'particularly when used in connection 'with an electric railway.

A still further object of this invention is to .provide a strong and durable rail joint wherein positive and reliable means are employed for preventing longitudinal creep ing of therails or ties; sleepers'or other rail supports, andprovisionis made to allow for expansion and' contraction of adjoining rail members. v .A still further object of this invention is to provide tie plates that maybe advantageously used in connection with my rail joint and my rails may be constructed for connection with ordinary rails when such connectionv is required. I V

e Other objects-are attained by the novel rails to eliminate the usual.

of the inner rail member.

A rail in accordance with my invention is composed of inner andouter members separat-ivelypro'duced and adapted to be placed togetherto term a continuous railstructure.

The outer membercomliirises ahead 1 formed with divergingweb portions 2fai1d lateral base fianges 3, the Web portions 2 providing the lower vpart of the; outer rail member livith longitudinal groove or way .4} .which v The inner rail member is-adapted, to-fit within the groove 4-01? the outer rail memher and comprises a base portion 5, a Web portion 6 and an auxiliary head portion 7,;' the webportion 6 being formed by concave walls ot' the inner rail member; which afior'd longitudinal recesses 8 throughout the length These recesses confront the'web portion 20f the outer rail member and thus :torm runways throughout the length of the rail structure. In these runways may be placed solider tubular members 9 which may be made ofvarious materials for various purposes. For instance the members 9 may be made ofrubber for deadening the noise incident-t0 rolling stock moving on the'head 1 ofthe outer rail section, and the "tubular rubber members may r v accommodate electrical connections em.- ployed for bondin'g rails or for transmitting ends of inner rail members.

. tening means.

currents necessary for the maintenance of signal systems in connection with a railroad. The members 9 may be Suitable electrical conductors throughout the length of the rail or may be in short lengths simply for bonding purposes at the adjacent ends of rail members.

In laying the track the joints of the outer rail members are placed intermediate the joints of the inner rail members so that there Will be a solid rail head 1 over the adjacent This arrangement will afford a solid inner rail member under adjacent ends of the heads 1 and it is in consequence of such alternate arrangement of oints that there will be practically a continuous railway for rolling stock.

In laying the rails on ties, sleepers or other rail supporting members 10 and'tie plates 11 are employed for supporting the rail members at any joint,,said tie plates being connected to the ties by spikes 12 or other tas- Each tie plate is formed with ribs 13 for engagin the lateral base flanges 3 of the outer rail members, and in addition to said tie plates, I may use rail bracesle, as best shown in Fig. 8. These rail braces may be spiked to the ties and 'engaged under the heads 1 of the outer rail members for firmly supporting said heads, particularly on any curved section of track. The bracesl l maybe used as splice bars at the oints ot outer rail members, and in some instances the braces may be dis ensed with and the'lateral flanges 3 spiked to the ties.

To preventlongitudinal creeping oi the inner rail members relative to ties or a road bed, one or both ends of each inner rail inei ber may be; provided with a depending stud or lug l5 to'engage in an opening 16 provided therefor in a tie plate or rail support.

hould it become necessary to connect one or" my improved rails to an ordinary rail 17, said rail may have its head and base cut away to leave a projecting Web tongue 18, and an inner rail member may have its ends slotted, as at 19,- to receive the Web tongue 18, thus connecting an ordinary rail lvly rail members may be rolled or other Wise produced and it is thought that the utility of the same will be apparent Without further description. li hile in the drawing there is illustrated the preferred en1bod iment of my invention, it is to be understood that the structural elements are susceptible of such changes, in size, shape and manner of assembling, as are permissible by the appended claims.

What I claim is 1. A rail comprising inner and outer members, one placed on the other and the inner member having concave Walls affording spaces between said members, and tubular sound deadening material in the spaces between said members and extending through- V out the lengthof said members.

2. A. rail comprising inner and outer 'n1em bers, one placedon the other and the inner member having concave Walls affording spaces between said members, the outer member having a head'and diverging Web portionsterminating in lateral base flanges, and sound deadening material in the spaces between said members.

In testimony whereof I atiii: my signature.
